Do you have a topic that is an immediate deal breaker if a manga series you were already reading suddenly featured that topic, such that you would stop reading the series (even if it was "tastefully" done)? For example: religion, rape, etc.

Looking for manga/anime

Im looking for a anime/manga where the MC is strong and knows what he can do but hides it and then in some chapter or episode his friend or the girl he likes or something along those those lines gets attacked then he goes berserk or something like that and basically nearly beats the guy to death. I also don't want him to be someone who starts of weak but has hidden potential and trains to get OP i want the guy to start, if not OP fairly strong compared to the rest of the guys around.

If none of the anime/manga you guy can think of from the top of your head resemble that then just any anime/manga will do but i prefer the other one more just because i have a urge to read that type of specific manga haha more than this one. I don't mind if later in the story he loses and gets a bit stronger though like that but just not starting off really weak

Edit:Similar manga/anime that i have read/seen from the top of my headChrome Shelled RegiosDensetsu no Yuusha no DensetsuTiji-kunRurouni Kenshin Mahouka koukou no rettousei
